How to find whether binary representation of a number is palindrome in C++

Answer 1

#include <algorithm>
#include <iostream>
#include <bitset>
  
bool is_binary_representation_of_number_palindrome(unsigned int num) {
    std::string binary = std::bitset<16>(num).to_string(); 
    binary.erase(0, binary.find_first_not_of('0'));
     
    std::cout << binary << "\n";
     
    std::string reversebinary = binary;
    std::reverse(reversebinary.begin(), reversebinary.end());
   
    return binary == reversebinary;
}
  
int main()
{
    unsigned int num = 153; // 10011001
 
    if (is_binary_representation_of_number_palindrome(num)) {
        std::cout << "Palindrome";
    } else {
        std::cout << "Not Palindrome";
    }
}
  
    
    
    
/*
run:
    
10011001
Palindrome
    
*/
